Today, cast - in - situ piles are more widely used in deep foundation engineering because of their many advantages, such as better adaptability to various ground condition, providing enormous bearing capacity by a single pile and smaller dosage of reinforcing steel bar. but, their own disadvantages, such as sediment under tip, clay slurry around pile, friction and tip resistance disagreement and initial ground stress freeing, limited their bearing capacity, lowered the utilization ratio of material and increased the settlement
灌注樁,因其對地層適應性強、能提供較大的單樁承載力、鋼筋用量少等優點,在目前深基礎工程中得到了極為廣泛的應用。但是,灌注樁的固有缺陷,諸如孔底虛土;孔壁泥漿;端阻、側阻發揮不同步;鉆孔后原地應力釋放等,限制了其承載力的發揮,使得材料利用率不高,沉降較大。Based on the results of vertical static loading test and stress test for longhole bored pile in loess foundation, by analysing the transferring law of axial force and the action of lateral friction resistance and bottom resistance, the paper discusses the influences of two types of holing technology on bearing capacity behavior
本文通過黃土地基中旋挖鉆孔灌注長樁和泥漿護壁鉆孔灌注長樁靜載荷試驗和樁身應力的測試,分析了黃土地基中兩種成孔工藝鉆孔灌注長樁樁身軸力的傳遞規律、樁側阻力及樁端阻力的發揮性狀,探討了兩種成孔工藝對鉆孔灌注長樁承載力的影響。The grouting test result shows that this technique of pile foundation construction is effective, it can not only increase the upper and skin friction of the cast - in - place pile, but also improve the bearing capacity of the cast - in - place pile, and gain a larger economic benefit for whole project at the same time
經樁端壓漿實驗結果表明,該技術可以增加鉆孔灌注樁樁端阻力和樁側壁摩阻力,是一項行之有效的樁基施工技術,它可有效提高鉆孔灌注樁的承載能力,同時提高經濟效益。The shear strength increases by 3 - 6 times after improvement through vane shear test and the resistance increases largely through cpt. the soft foundation treated by vacuum combined with surcharge preloading is very effective. second, the mechanism and some problems of vacuum combined with surcharge preloading were analyzed
通過十字板剪切試驗與靜力觸探試驗,加固後土體的抗剪強度一般可提高3 6倍,錐尖阻力與側壁阻力也有大幅增長,說明真空聯合堆載預壓加固軟土地基的效果顯著。There are a lot of advantages when inner trachea applied in air pre - heater, such as the improvement of the temperature of pipe, the low consumption of metal, except for the increment of flow resistance. according to many related papers, it is more proper inner trachea with the structure of short distant between two whorls and shallow depth of whorl. it can enhance heat transfer with smaller flow loss
內螺紋管是一種異形管,和光管相比,管內側的換熱系數大大增強了,應用於空氣預熱器可以起到提高總傳熱系數、節約受熱面金屬消耗量的目的;同時提高了管壁溫度,能夠減輕低溫腐蝕的程度和速度;不足之處是帶來了更大的阻力損失。The reliability is validated further on. 3. the static loading test is modeled by plaxis, based on this, the basic bearing mechanism is analysed which comprise the rule of the load - settlement curves, inner and outer friction resistance, end bearing, stress distribution along pile depth and the dissipation of excess pore pressures
應用plaxis程序模擬單樁靜載荷試驗的過程,並根據計算結果較為詳細的分析了pcc單樁的基本承載特性,主要包括荷載?沉降曲線的特徵、樁壁內外側摩阻力的分佈、樁端阻力的分佈、樁的軸向荷載傳遞以及孔壓消散規律等。分享友人
